Re: libidn2 2.0.5 fails test-lookup on debian sid arch=ppc64

[Tim Rühsen]

Hi Dennis,

there is something going on that I do not understand.

The code in libidn2 checks some combinations of input flags, the code is
pretty simple. In two cases the check says OK instead of the expected
error. I don't see any endianess issues there, but maybe I am blind.

The following combinations of flags should give an error:
IDN2_NONTRANSITIONAL|IDN2_TRANSITIONAL
IDN2_NONTRANSITIONAL|IDN2_NO_TR46
IDN2_TRANSITIONAL|IDN2_NO_TR46
IDN2_TRANSITIONAL|IDN2_NONTRANSITIONAL|IDN2_NO_TR46

But your log shows #2 and #3 return OK (expected rc -209 got rc 0).

The code is
if (((*flags) & IDN2_TRANSITIONAL) && ((*flags) & IDN2_NONTRANSITIONAL))
  return IDN2_INVALID_FLAGS;

if (((*flags) & (IDN2_TRANSITIONAL|IDN2_NONTRANSITIONAL)) && ((*flags) &
IDN2_NO_TR46))
  return IDN2_INVALID_FLAGS;

Where/how did you get the sources (git or tarball) ?
Did you 'make clean' before 'make && make check' ?
What is the ouput of 'ldd tests/test-lookup' ?

Do you have a Dockerfile so that I can reproduce locally (or anything
else to reproduce) ?

Regards, Tim
